Model discussion - hunt for cold - Christmas countdown


Paul
Message added by Paul,

Please remember this is a model based discussion - some chat is ok, but a weather model related theme should run throughout.

The guiding principles of everyone's participation in this thread are:
Be kind -- Stay on topic -- Share your knowledge -- Be polite -- Be honest -- Be tolerant -- Be family friendly

For a less frenetic look at the models head over to the alternate model discussion

    Can we just not comment on the ICON  
    Big runs coming now, things can still fall apart but I feel a good set of runs this afternoon and we should be safe for a decent cold spell at least!!
    Oh noMETO has set the scene !!  Some wording change here I think!!

    Yep, too far North on the ICON and not even Scotland is getting snow on Christmas day. Let's be honest, it's model fodder 99% of the time. 

    One of the issues we have is that Western Europe is not cold. A SE off the continent will not be of much help given the 850s, really need the front to slow or go so far south we pull in a NE wind.

    Well, what can I say.. …the GEFS / ECMWF mean is trending colder from the N / NE in the mid range which is potentially great news for Christmas,  how cold?, how wintry is for nearer the time…anyway, Christmas is coming, the goose is getting fat, the mean is trending colder..I’m more than happy with that! :santa-emoji::reindeer-emoji: ❄️ ⛄️

    Why we pay attention to the icon is beyond me!!!yeh i know why because its the first of the crappy models to come out!!!!theres a reason i dont comment on it and no its not cos its not showing what i want!!!its cos its a rubbish model!!a lot of my peeps would save themselves a lot of frustration if they just wait for the 12z gfs to come out first and take it from there!!!i get it its easier said than done but we gota resist sometimes!!!its a cannon fodder model and not in the same league as the crappy GEM let alone gfs lol!!!

    The longer range forecast is not too shabby though  

    The 12z ICON is not what we want but unless the rest of the 'big guns' follow suit I'm not too concerned.

    Fingers crossed for further improvements on the GFS and UKMO from this morning's runs for us coldies!

    It's very fluid given the strength of the block. Still many changes to come both ways

    @Paul excellent idea with the theme for the new thread...very good spirited if I may say.

    @Ali1977 that update contradicts itself if you read the 1st part...milder to the South,before ending with rather cold and settled! And the bigger picture has not changed moving further forward!

    I don't think for 1 minute the 12s are gonna nail this down...it looks like a Battleground type scenario towards Xmas with a front moving in...we've seen these grind to a halt and even be 100miles out more than once. Well we very often came across those scenarios back in the 80s...and that's what we need to be looking at if this winter is to shape up going on the teleconnections that it could be.

    Icon not great...but let's be honest it may have had a couple shots at fame in years..perhaps 1st to pick up 2018s beast..not sure on that though..And secondly the failed 2019 Estly spell...when all other models followed it....can't think its done much else since then tbh!

    Regardless of the runs through this evening things are far from sorted for the Xmas period...could be Tuesday or Wednesday next week tbh.

    And unless mushy or John come on later or Sunday to say noaa have backtracked big time,which at this stage I would say unlikely) all good in the good as far as this geezer is concerned.

    ‘Although it wouldn’t really mean a great deal, it would be nice to see Ukmo day 4/5 strengthen the ridge ahead of the trough and therefore disrupt it somewhat days 5/6 (and to absorb that shortwave into the scandi trough) 

    would be a decent day to have all the ops on the same page for wed through Friday at least. (Assuming that’s good for a widespread white Xmas !)

    Only if it does not show what people want to see. 
    If it showed a raging easterly, It would be regarded as a good model.
